You have to give the holotape to the Brotherhood for the Blind Betrayal mission to become available. It is the holotape that reveals Danse is a Synth. Although, even if you save Danse from that mission, then he won't be your companion anymore if you side with the Institute. The only way to keep Danse as a companion is to side with the Minutemen and never go to war with the Brotherhood or side with the Brotherhood and never have Danse around the Brotherhood since they don't take kindly to known Synths.
